Abstract:
Alternaria blight disease caused by Alternaria triticina is most important disease of wheat in Central zones (NEPZ) representing warm and humid climate in India. It is also increasing in Madhya Pradesh, due to climate changes and causes considerable losses in susceptible varieties. A total of 78 wheat varieties/genotypes and 325 CMS F1 hybrids wheat genotypes were screened in field conditions during 2021-2022 as part of the wheat improvement project under JNKVV-Jabalpur to test their resistance. Out of 78 wheat varieties were screened, 6 varieties were found highly resistant, 27 were resistant, 33 were moderately resistant, 7 were moderately susceptible and 5 were susceptible to Alternaria wheat blight. Out of 325 CMS hybrid wheat genotypes were screened, 22 were found highly resistant, 112 were resistant, 113 were moderately resistant, 68 were moderately susceptible, 8 were susceptible and 2 were highly susceptible to Alternaria blight of wheat.
